Johnson Controls C450YNN-1 Power Module 24V-120V-240V

The Johnson Controls C450YNN-1 Power Module is arguably a common component of most existing HVAC systems. It also acts as a voltage converter where it converts the actual voltage of 120V or 240V AC, 50/60 Hz to a mere 24V AC. This low voltage supplies control circuits of HVAC equipment ensuring safe and efficient operation. Regard it as a device that steps down the voltage from the mains to an appropriate level for the delicate control circuits of your HVAC system. This small and portable unit is functional in a broad range of temperatures (-34°C to 66°C) and is housed in a NEMA 1 enclosure that shields it from dust.
